    "description": "Gemini Omni Flash 1.2 is Google's multimodal video model for generating, editing, and extending clips with native synchronized audio. It generates up to 15 seconds from text or a single starting image, edits source videos of up to 15 seconds with optional reference images, and keeps characters, products, and brand details consistent across reference images and videos. Output runs from 360p for quick drafts to 1080p and 4K for delivery, which suits high-volume work such as product clips, virtual try-ons, and ad variations.",

Each item can be either a plain image input (UUID, URL, Data URI, or Base64) or an object that pairs an image with a target position in the video.\n\nThe `frameImages` parameter allows you to constrain specific frames within the video sequence, ensuring that particular visual content appears at designated points. Position can be specified using `frame` (named positions or frame indices) or `timestamp` (seconds), depending on model support. This is different from `referenceImages`, which provide overall visual guidance without constraining specific timeline positions.\n\nWhen the `frame` parameter is omitted, automatic distribution rules apply:\n\n- **1 image**: Used as the first frame.\n- **2 images**: First and last frames.\n- **3+ images**: First and last frames, with intermediate images evenly spaced between.\n\n**Examples**:\n\n**Shorthand format:** When you don't need to specify a frame position, you can pass a plain image input directly.\n\n```json\n\"frameImages\": [\n  \"aac49721-1964-481a-ae78-8a4e29b91402\"\n]\n```\n\n**Object format:** When you need to specify a position, use an object with `image` and either `frame` or `timestamp` (model-dependent).\n\n```json\n\"frameImages\": [\n  {\n    \"image\": \"aac49721-1964-481a-ae78-8a4e29b91402\",\n    \"frame\": \"first\"\n  }\n]\n```\n\n**First and last frames:** With two images, they automatically become the first and last frames of the video sequence. You can mix shorthand and object formats.\n\n```json\n\"frameImages\": [\n  \"aac49721-1964-481a-ae78-8a4e29b91402\",\n  {\n    \"image\": \"3ad204c3-a9de-4963-8a1a-c3911e3afafe\",\n    \"frame\": \"last\"\n  }\n]\n```\n\n**Multiple frames:** With three or more images, the first and last are anchored while intermediate frames are evenly distributed across the timeline.\n\n```json\n\"frameImages\": [\n  {\n    \"image\": \"aac49721-1964-481a-ae78-8a4e29b91402\",\n    \"frame\": \"first\"\n  },\n  \"c00abf5f-6cdb-4642-a01d-1bfff7bc3cf7\",\n  {\n    \"image\": \"3ad204c3-a9de-4963-8a1a-c3911e3afafe\",\n    \"frame\": \"last\"\n  }\n]\n```\n\n[Read full documentation](https://runware.ai/docs/models/google-gemini-omni-flash-1-2#frameImages)",
